1d array texture
Genetic texture class. It can support any target.
Definition: texture.hpp:12
texture1d_array()
Create an empty texture 1D array.
Namespace where all the classes and functions provided by GLI are exposed.
Definition: comparison.hpp:15
1d texture
Definition: texture1d.hpp:13
genType load(extent_type const &TexelCoord, size_type Layer, size_type Level) const
Fetch a texel from a texture. The texture format must be uncompressed.
extent_type extent(size_type Level=0) const
Return the width of a texture instance.
format
Texture data format.
Definition: format.hpp:12
Include to use 1d textures.
texture1d operator[](size_type Layer) const
Create a view of the texture identified by Layer in the texture array.
void clear()
Clear the entire texture storage with zeros.
void store(extent_type const &TexelCoord, size_type Layer, size_type Level, genType const &Texel)
Write a texel to a texture. The texture format must be uncompressed.
